How to BalanceSO2 + NaOH = NaHSO3

How to Balance Sulfur dioxide + Sodium hydroxide → Sodium hydrogen sulfite

Type of Chemical Reaction: This is a combination reaction.

Word Equation: Sulfur dioxide + Sodium hydroxide → Sodium hydrogen sulfite

Balancing Strategies: This is a combination reaction and should be fairly straightforward to balance. Be careful counting the oxygen atoms!

Hint-2

For a complete explanation, watch:

When balancing chemical equations our goal is to have the same number of each type of atom on both sides of the equation.

Only change the coefficients (these are the numbers in front substances).
Coefficients are the numbers in front of the molecule.

Never change the subscripts (the small numbers after elements).
Coefficients are the numbers in front of the molecule.
